Difference between Combination and Decomposition Reaction
These are some of the key differences between both combination and decomposition reactions :
Combination Reaction vs. Decomposition Reaction | ||
|---|---|---|
| Property | Combination Reaction | Decomposition Reaction |
| Definition | A reaction where two or more substances combine to form a single product. | A reaction where a single compound breaks down into two or more simpler substances. |
| Reactants | Two or more elements or compounds. | A single compound. |
| Products | A single compound. | Two or more elements or compounds. |
| Energy Change | Often release energy in the form of heat or light. | Often require an external energy source (such as heat) to initiate the reaction. |
| Example | 2Mg + O2 → 2MgO | 2H2O2 → 2H2O + O2 |

Decomposition Reaction
Have you ever wondered what happens when compounds break apart into simpler substances? Or how energy is released, and new compounds are formed? The answers to these questions lie in the concept of Decomposition Reaction. Decomposition Reactions are a key concept in the understanding of the chemical breakdown of a complex substance. In this article we will learn about this reaction in detail, also we will learn various examples and their types as well. So, let’s start the article by answering the question “What is a Decomposition Reaction?”.
